<p>All lines are drawn with rounded corners and end caps. Different join and 
line end styles can be created by drawing line segments as a sequence of filled 
shapes. With 1 twip equal to 1/20th of a pixel this technique can easily be 
used to draw the narrowest of visible lines.</p>

<p>Whether the alpha channel in the colour is used is determined by the class 
used to define the shape. Transparent colours are only supported from Flash 3 
onwards. Simply specifying the level of transparency in the Color is 
not sufficient.</p>

<h2>History</h2>

<p>SolidLine represents the LineStyle structure from the Macromedia 
Flash (SWF) File Format Specification. It was introduced in Flash 1. Support 
for transparent colours was added in Flash 3.</p>
